I built a tool that detects broken security headers, missing robots.txt, and WP_DEBUG=true — then opens a PR to fix them automatically
A new tool called DevLab has been developed to automatically detect and fix common web issues such as broken security headers and missing robots.txt files. It integrates with GitHub and GitLab to open pull requests for review after generating fixes. The tool aims to streamline the workflow for web agencies dealing with recurring problems in client sites.
- ▪DevLab detects issues like WP_DEBUG being set to true and missing security headers.
- ▪It generates fixes and opens pull requests for user review, ensuring transparency in changes.
- ▪Each fix comes with a confidence score to indicate its reliability.
